In this work, by the reaction of salicylaldoxime (H₂Saox), isobutyric acid (HⁱBuac), and Ti(OⁱPr)₄ the hexanuclear titanium oxo cluster (TOC) of[Ti₆(μ₃-O)₄(Saox)₂(ⁱBuac)₄(OⁱPr)₈] (1) was solvothermally synthesized, and by the reaction of acetohydroxamic acid (H₂Ahox), phenylphosphonic acid (PhPO₃H₂) and Ti(OⁱPr)₄ the octa-nuclear TOC of[Ti₈(μ₃-O)₂(Ahox)₂(PhPO₃)₄(OⁱPr)₁₆] (2) was prepared. Both of them were characterized by IR, elemental analyses, and single-crystal X-ray diffraction. Spectral experiments indicate that the two complexes have absorptions in the visible region. The band gaps of complexes 1 and 2 were 2.43 and 2.61 eV respectively. Complex 2 is the first H₂Ahox-based TOCs that showed photocatalytic H₂ evolution activity with the rate of 140.2 μmol·g^-1·h^-1.
